Specification of Letters Patent.

Application filed August 18, 1915. Serial No. 46,024.

To all whom it may concern:

Be it known that I, ARNOLD SOHROETTER, a citizen of Austria, and a resident of New York city, in the county and State of New York, have invented certain new and useful Improvements in Safety-Catches for Pins, of which the following is a specification.

This invention relates to a safety catch of novel construction for breast pins and simi lar articles of jewelry which may be readily manipulated and eifectively locks the same against surreptitious removal.

In the accompanying drawing: Figure 1 is a front view of the base plate of a breast pin provided with a safety catch embodying my invention; Fig. 2 a section on line 2-2 Fig. 1; Fig. 8 a section on line 33 Fig. 2; Fig. 4 a section on line H Fig. 2, and Fig. 5 a section similar to Fig. 3, showing the parts in a different position.

To one end of the base plate 1 of a suitable article of jewelry is hinged at 2 a re silient pin 3 as usual. At its other end, plate 1 is provided with a keeper 4:, having is fastened to the plate, and an upper barreled hook 6. Hook 6 telescopes an axially movable tubular slide 7, the head 8 of which is adapted to bear against the outer end of the hook and is furnished with finger pieces 9. Head 8 has a downward extension 10, to which are secured two forwardly extending guide rods 11 and 12. Of these, rod 11 passes through an aperture 13 of cross bar 5, while rod 12 is received within a cylinder 14 carried by said cross bar. Within this cylinder is housed, a spiral spring 15 that encompasses the rod, and abuts against a head 16 thereof, the stroke of the rod within the cylinder, determining the play of slide 7.

To close the catch, pin 3 is slipped under hook 6 so as to rest with its points against the side of slide 7. The latter is then retracted to cause the pin to spring into axial alinement with the slide-socket (Fig. 5), and then the slide is released so as to be projected by spring 15, over the end of the pin, and thus securely lock the latter within the keeper. By withdrawing the slide, the pin will become unlocked, so that it may be slipped out of the keeper, and the catch be opened.

I claim:

A safety catch for pins comprising a base plate having a pair of apertures, a hookshaped keeper mounted thereon, a tubular slide engaging the keeper, a pair of rods connected to the slide and engaging the base plate-apertures, and a spring engaging one of said rods.
